Solubility is defined as the concentration of a solute in a solvent when the solution becomes saturated at a specific temperature and pressure. It is expressed as:
- Molarity (M): Moles of solute per liter of solution (mol/L).
- Molality (m): Moles of solute per kilogram of solvent (mol/kg).
- Parts per million (ppm): Milligrams of solute per liter of solution, often used for very low solubility levels.
- Percentage concentration: Expressed as weight/volume (% w/v) or weight/weight (% w/
